RUNNING-GEAR.

SPECIFICATION forming part of Letters Patent No. 627,833, dated June 27,1899.

' Application filed March 4,1399. Serial No. 707,750. (No model.)

To all whom it may concern:

Be it known that I, GEORGE F. UEBEL, of l following is a full, clear,and exact description.

Thisinvention relates to running-gears for all vehicles; but it isespecially adapted to the runninggears of agricultural separators, the

purpose being to provide an improved construction of the gearing tofacilitate the movement of vehicles and also to assist in turning thembycausing both axles to swing in the act of turning.

This specification is the disclosure of one form of my invention, Whilethe claims define the actual scope thereof.

.Reference is to be had to the accompanying drawings, forming a-part ofthis specification, in which similar characters of reference indi-. catecorresponding parts in all the views.

Figure 1 is a plan-view of the invention. Fig. 2 is a side elevationthereof. Fig. 3 is a fragmentary rear end elevation, and Fig. 4 is adetail section on the line 4 40f Fig. 1.

The sills 1 of the running-gear are joined to the rear bolster 2 and thefront bolster 3, so as to form a single rigid structure. The drawingsshow the invention applied to a separator-frame, and in Figs. 1, 2, and3 the fanbox is designated by the number 4. This box extends across therunning-gear between the bolsters and is joined to the sills 1, as shownin Figs. 1 and 2. Beneath the box 4 a transversely-extending brace 5extends, the ends of such brace being connected with hangerarms 6,serving to support the brace and the box 4.

The front axle 7 is joined to the bolster 3 by means of bearing-plates 8and 9, as illustrated in Fig. 4, and the front axle has a brace-rodortruss 7 (see Fig. 2) to strengthen the same. The plate 8 is providedwith a pair of U-bolts 10, embracing the bolster 3 and serving to holdthe plate rigidly against the under side of the bolster. This plate isformed with a circular ball-race matching with a similar ball-race inthe plate 9, which plate 9 is secured to the axle 7 by means of twoU-bolts 11, similar to the U-bolts 10. A

pivot-stud ,12 is formed on the plate 9, and this-stud 12 projectsthrough a central opening in the plate 8, so as to pivotally mount theplate 8 on the plate 9, and thereby support the front bolster. Theball-races of the antifriotion-balls 13, which reduce the frictionbetween the two plates.

The rear axle 14 is arranged to support the bolster 2 by means ofbearing-plates 15 and 16, similar to the plates 8 and 9, held inposition by U-bolts 17 and 18, similar to the bolts 10 and 11. The rearaxle has a bracerod or truss 14, similar to the truss 7 Rolling onantifriction-rollers 19, mounted, respectively, on the ends of the axle14, are two. arc-shaped track-plates 20, the ends of each plate beingfastened to the rear portions of the respective sills 1 by means ofblocks 21 and the middle portions of which are fastened to the underside of the bolster 2, at the end portions thereof, by means ofupwardly-extending lugs 22, formed on the track-plates. By these meansthe axles 7 and 14 are mounted to turn beneath the rigid framing of therunning-gear, which is formed of the sills 1 and bolsters 2 and 3.

In order to cause both axles to swing as the vehicle turns, and thusfacilitate the turning thereof, '1 provide two cables 23, which arerespectively seized to eyes 24, located one at each end of the rear axle14, from which eyes the cables 23 are led forwardly and rove aroundidler-pulleys 25, carried, respectively, in the ends of the brace 5.From the idlerpulleys 25 the cables 23 are led across each other andforwardly to the front axle 7, where they are seized to eyes 26,attached to said axle. As indicated by the dotted lines in Fig. 1, asthe front axle 7 swings the cables 23 serve to swing the axle 14 in sucha manner as to turn both trucks of the vehicle, and thus enable thevehicle to turn ina very short space. 7 Should it be not desired toemploy the cables 23, they may be disconnected from the eyes 26 andhauled taut through eyes 27,

fastened, respectively, to the under'sides of the sills 1, near thefront ends thereof. These cables 23 will then serve to hold the rearaxle 14 in proper position with respect to the bolster 2 and therunning-gear will in turning act the same as in the ordinary structure.The

cables are provided with turnbuckles 23, which are located at the frontends of the cables and by which the tension of the cables may beregulated.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a running-gear, the combination of bolsters,sills rigidly attached thereto, two curved track-plates attached to oneof the bolsters respectively at the ends thereof and projecting at thefront and rear of the bolsters, each track-plate having lugs engagingthe bolster and having blocks at their ends connecting them rigidly withthe sills, and antifriction-rollers mounted on the axle beneath thetrack-plates and respectively engaging the track-plates.

2. In a running-gear, the combination of bolsters, sills rigidlyattached thereto, two curved track-plates attached to one of thebolsters respectivelyat the ends thereof and projecting at the front andrear of the bolster, each trackplate having lugs engaging the bolsterand having blocks at their ends connecting them rigidly with the sills,antifriction-rollers mounted on the axle beneath the track-plates andrespectively engaging the track-plates, and cables having their endsrespectively attached to the axles, the cables being crossed between theaxles.

3. The combination with a bolster and axle, of a bearing-plate having acircular ball-race in its under side, U-bolts fastening thebearing-plate to the bolster, a second bearingplate having a ball-racein its upper face matching With the ball-race in the firstbearing-plate, the second bearing-plate having a central stud mountedrigidly thereon and extending through a central opening in the firstbearing-plate to turn in the same, U-bolts securing the secondbearing-plate to the axles,

and balls mounted to run in the races.

4C. In a running-gear for agricultural separators, the combination ofsills, a bolster rigidly attached thereto, a fan-box held by the sills,a brace extending beneath the fan-box and supported from the sills, anidler-pulley held at each end of the brace, axles mounted to turnbeneath the respective bolsters, and cables, the ends of which arerespectively attached to'the axles, the cables being rove around theidler-pulleys and crossed between the axles.
